Is One Barrel of Engine Oil Enough for an Oil Change?

[JourneyLynn]

For an engine oil change, one barrel is generally sufficient, typically filling about three-quarters of the barrel. Principles of Engine Oil Refill: The amount of lubricating oil should be maintained between the upper and lower marks on the oil dipstick. Excessive lubricating oil can seep into the combustion chamber through the gap between the cylinder and piston, forming carbon deposits. These deposits can increase the engine's compression ratio and raise the likelihood of knocking. Key Features: The engine is the heart of a car, and only qualified lubricating oil can reduce wear on engine components and extend their service life. Engine oils on the market can be broadly categorized into mineral oils and synthetic oils based on their base oil (vegetable oils are not considered due to their scarcity).
